OVEN FOR DRYING OR BAKING- GOAIED METAL VESSELS OR OTHER ARTICLES.

: Specification of Letters Patent.

Patented Feb. 10, 1914 Application filed May 28,1910. Serial No. 563,866.

To all whom it may concern:

Be it known that I, FRANKLIN RUDOLPH, a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Ovens for Dr ing or Baking Coated Metal Vessels or 01; er Articles, of which the following is a specification.

My invention relates to improvements in ovens for drying or baking painted, lacquered or coated sheet metal vessels or other articles.

The object of my invention is to provide an oven of a simple, efficient and economical construction, by means of which sheet metal vessels or other articles, after being lithographed or coated with paint, lacquer or other coating, may be rapidly and cheaply dried or baked and with a. minimum expenditure of time and fuel. 7

My invention consists of an oven chamber having an entrance opening for the articles to be baked at its lower portion at one end and an opening for said articles at its lower portion at the other end, and an upwardly extended intermediate portion above the entrance and the exit openings, of an endless flexible conveyer extending into the oven chamber at the entrance end and traversing the same in a plurality of runs extending between the upper and lower portions of the oven chamber, and preferably consisting of a pair of endless flexible chains furnished with a series of article supporting rods extending betwen the chains and provided with a plurality of pivotal article supports, each preferably a wire hook adapted to receive a coated vessel in an inverted position and to convey it up and down in and through the oven chamber in such inverted position.

It further consists in combination with the above, of an inclined drip board' at the entrance end of the oven chamber and under neatl-L the article supports of the oven-chamber toffake the drip from the freshly coated vessels or other articles as they are carried into the oven chamber bythe endless conveyer.

It further consists in the novel construction of parts and devices and in the 'novel combinations of parts and devices herein shown and described and more particularly specified in the claims.

In the accompanying drawing forming a part of this specification, Figure 1 is a central, vertical, longitudinal section of a bak- 1n g or drying oven embodying my invention. F1 2 is a vertical cross section on line 2--2 of ig. 1. Fig. 3 is a central, vertical, longitudinal section illustrating a modification, and Fig. 4 is a front elevation of the constrnction shown in Fig. 3, the ceiling of the room containing the ovenbeing indicated in section.

In the drawing, 1 represents an upright oven, its walls being preferably of buck or masonry, and having an entrance opening 2 in its front end 3 at the lower POI'tlOIlqOI' bottom thereof and an opening 4: in its rear end wall 5, the intermediate elevated portion 6 of the oven chamber extending upwardly to a considerable height above the openings 2, and 4.

.7 is an endless flexible conveyer extending into the oven chamber at the entrance opening 2 near its lower portion and upwardly and downwardly through the oven chamber to the opening 4 thereof in a plurality of upright runs 8, 9, 10, 11, and thence out through the entrance opening 2 in a horizontal run 12. The endless fiexibleconveyer .7 preferably comprises a pair of chains. 13, 13, furnished with article supporting rods 14; extending between the chains at intervals, and furnished each with a plurality of swivel or pivotal article supports 15. The article supports 15 each preferably consists of a wire hook adapted to receive a coated sheet metal vessel 16 in an inverted position, and provided with an eye 17 to give it a pivotal or swivel connection with the supporting rod 14 of the conveyer.

The conveyer chains 13, 13 travel over or around pulleys or sprocket wheels 18, 19, 20, 21, 22, '23, the sprocket wheel 18 being outside the oven chamber near the entrance end thereof and the sprocket wheel 23 near the opening 4 of the oven chamber, and sprocket wheels 20, 22 being in the upper portion of the oven chamber and sprocket wheels 19, 21 at the lower portion thereof. Each pa-lr of sprocket wheels is preferably secured to'a common shaft 24, the same being journaled in suitable brackets or hangers 25.

26 is the driving pulley-for operating the conveyer, the same being secured to the shaft of one pair of sprocket wheels.

An inclined drip board or trough 27 is arranged under the upper horizontal run 28 of the conveyer 7 at the entrance end of the oven chamber to collect the drip from the freshly coated vessels 16 as the are-being carried into the oven chamber y the ends less conveyer. As the coated sheet metal vessels or articles 16 to be baked or dried are suspended by pivotal supports from the conveyer, they will be carried up and down The coated vessels or articles 16 are placed on the ivotal supports or hooks 15 suspended om the supporting rods 14 of the endless flexible conveyer 7 as the conveyer chains pass around the sprocket wheels 18 at the entrance end of the oven and the baked or dried vessels orarticles are removed from the supports or hooks 15 as the conveyer {7 moves past the exit opening 4 at the rear end of the oven chamber.

The oven chamber is preferably heated by means of a series of gas burners 29, the same preferably consisting of jet 0 enings in gas supply pipes extending t rough the oven chamber at the ;lower portion thereof-,and preferably just above the openings 2 and 4.

In the modification shown in Figs. 3 and 4 of the drawing, the walls of the oven chamher are illustrated as being made of sheet steelor other metal and the conveyer has run of the rods being furnished with a series of pivoted conveyer havinga substantially horizontal run and a plurality of upright runs for carryin the articles to be baked or dried into an up and down through said chamber, anda drip board under said horizontal fi d conveyer, substantially as speci- 2. In an oven for drying or baking coated vessels or other articles, the combination with an oven chamber having an entrance opening at one end and an opening at the other end and an upwardly extended intermediate portion between said openings, of

'a conveyer for carrying the articles to be baked or dried into and up and down through said chamber from the entrance opening to said other opening, said conveyer comprising a pair offconveyer chains and a plurality of article supporting rods extending between said chains, said supporting supporting'hooks adapted to receive vessels .in an inverted position and suspend the same in such position continuously as they are conveyed into and up and down through the oven, substantially as specified.

3. In an apparatus of the character described, an oven chamber and a conveyer for carrying articles to be baked through said chamber, said conveyer havin a plurality of transversely extending rods, each rod having a plurality of independently pivoted supporting hooks mounted thereon, substantially as specified.
